UNITED STATES, BATES OFEIQE-Fr MARCUS L. BRowN, or DECATUR, easiesVENTILAT'QIN'G APPARATUS.

To all whom it may concern:

Be it known that I, MARCUS L. BROWN, a citizen of the United States ofAmerica, and resident of Decatur, in the county of Dekalb and State ofGeorgia, have invented certain new and useful Improvements inVentilating Apparatus, of which the following is a specification.

This invention relates to ventilators and particularly to means forpreventing the accumulation of moisture, gases, injurious vapors or heatin store houses and particularly for ventilating masses of cotton seedwhen stored in a bin or loft. 7

An object of this invention is to provide novel supporting means andventilating means to accomplish the result stated, the same to be usedin connection with buildings having floors with spaces thereunder or inconnection with floors which cannot receive currents of air from below.

'A further object of this invention is to provide a ventilator of thecharacter'indicated which may be made of difi'erentma- 'terials andwhich may be differently shaped according to the requirements inpractice.

With the foregoing and other objectsi n View, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention indetail, -reference will be had 7 to theaccompanying drawings forming part of this specification in which likecharacters denote corresponding parts in the several views, and inwhi'ch Figure 1 illustrates a view in elevation, partly in section of aventilating column embodying one form of the invention;

Application filed February 21, 191a s ns-1 noxzvaa's'a line-corresponding with the line -77 of ig- I Fig. 8 i'llustrates asectional View on the line 8-8 ofFig. 5; and

Fig. 9 illustrates a sectional viewon the line 9-9 of Fig. 6.

In these drawings'15 "and1'6 denotes members of a T-shaped post whichconstitutes the frame of the column shown in Fig. l, the member 16having beveledends as shown at "17 for engaging the wire netting 18which, in the present embodiment of the in vention, is shown as tubularand tapering from the bottom flange 19'to the top flange 20', it beingthe purpose ofthe inventor to have the bottom flange 19'secured to afloor and the top flange 20 connected to a ceiling through which latteran opening may be formed to permit the circulation necessary toventilate the binror room in which the column is stationed,.and itisalso, the purpose of the inventor to have an aperture in the floor,the said aperture being surrounded by the flange 19 :so that air maypass from the bottom to the top of theflcolumn, and aid in carrying awaythe heat which might be generated in a pile of cotton seed.

In Fig. 3, the sheathing21 of the column I is made of foraminousmaterial, preferably sheet metal, and it is supported by a framestructure such as is shown in'Fig. :4, the dif ference between thesheathing in Figs. 3 and i bei-ngthat the sheathing QZinFig. 4 consistsof. wire netting. I V y The frame structure of Figs. 3 and 4 consists'ofaseries ofhoops orlrings 23 to which the sheathing may be secured byfastenings such as 24 and these hoops or rings 23 are connected togetherby vertically disposed strips such as 25, any number of which may beemployed, and the vertically disposed strips are 'sec'ured to the'rings-or hoops by fastenings such as 24 which may pass through the sheathingas well as through the strips and hoops.

In the constructions noted, a bottom flange 26 and a top flange 27 maybe employed having the same functions as the flanges 19 and 20 describedin connection with the disclosure in Fig. 1.

In Fig. 4, however, provision is made for supplying air to the column inan eventthe ventilator is employed in buildings where the floor isconcrete or where it is not supported clear of the ground. When suchconditions are encountered, the flange 26 may be placed on the upper sidof a duct 28 which may be supported on the floor, and the end or ends ofwhich may project through the wall of a building and communicate withthe external atmosphere, so that the circulation of air can be insuredthrough the said duct and through th column. In Fig. 4:, I have alsoshown the top flange as being connected to a ceiling 29 which ha anaperture 30 for the passage of air, it being understood that thebuilding may be constructed in any approved way so long as there isprovision for the escape of air at the top and for the admission of airat the bottom of the column.

In Fig. 5 a modified construction is illustrated, consisting of a frame31 of the general structure of the frame illustrated in Fig. 4, the samebeing supplied with a sheathing of wire netting 32 and flange 33 whichlatter are also similar to the sheathing and flange shown in Fig. 4:,but in the construction shown in Fig. 5, the flange 33 is formed as acontinuation or at least is carried by a metal jacket or covering 34which telescopes on the netting 32 fitting the outside of the saidnetting and extending approximately half way down the post orventilating column. It is encircled by clamps consisting of bands 35with outturned ends forming ears 36 and 37 which are drawn together by abolt 38 so as to exert pressure on the jacket to bind it against thenetting 32. This jacket or covering serves two; purposes one to increasethe draft or suction through the ventilator by confining the heated airwhile it is passing through the top and its second purpose is to permitthe ventilating posts to be adjusted for different heights of loftsafter which it can be clamped in position and so held. A ventilatingcolumn made in accordance with this last mentioned construction preventsdissipationof the air and confines it somewhat after th manner of astove pipe and it results in increasing the draft and efficiency.

In Figs. 6 and 9, I have illustrated a still further modification inwhich the column comprises angular vertically disposed corner plates 39held in spaced relation to one another by the bands 40 to form a frame,the said frame being embraced by a wire netting 41 so as to form acolumn which is square in plan. In this construction, the upper flange42 and the lower flange 43 are of substantially the same construction asthe flanges 19 and 20 except as to their configuration and theirfunctions and purposes are the same.

By reason of the foregoing description and illustration it will be seenthat the invention is susceptible of wide margin of modifications andthe inventor does not, therefore, wish to be limited with respect to theexact details of construction since the invention resides in the broadidea as well as in the detail of construction appearing in the claims.

I claim 1. In a ventilating device, a frame, foraminous materialencircling the frame and spaced therefrom at points in its circumferenceto form a column having vertical air passages, a flange at the upper endof the column, and a flange at the lower end of the column for anchoringthe column.

2. In a ventilating device, a foraminous column, a sleeve constitutingan extension of the said column, said sleeve comprising a tubular sheetmetal member and clamping bands encircling the said member for causingthe said member to frictionally engage,

the column whereby the said member is telescopically mounted on thecolumn and secured at different positions of adjustment.

3. In a ventilating device, a foraminous column, a sleeve constitutingan extension of the said column, said sleeve comprising a tubular sheetmetal member and clamping bands encircling the said member for causingthe said member to frictionally engage the column whereby the saidmember is telescopically mounted on the column and secured at differentpositions of ad ustment, and a flange carried by the said member adaptedto be secured to a ceiling.
